VAPOR-BURNER.

SPECIFICATION forming part of YLetters. Patent No.270,194, dated January 2, 1883,

Application filed October 13. 1882. (No model.)

To all whom it may concern Y shown at C.

Be it known that I, T. TRAsK W o onwAan, a citizen ofthe United States, residing at Pana, in the county of Christian and State of Illinois, have invented a new and' useful Improvement in Vapor-Burners, of which the following is a specification d My invention relates to new and useful improvements in vapor-burners# and it consists in certain novel details of construction and arrangement, as willl be hereinai'ter more fully described, reference being had to the accom- 'panying drawings, in which- Figure 1 is a side elevation, partially in section, showingthe interior construction ofits irnproved parts. Fig. 2 is a top plan of the lower or generator portion ofthe burner. Fig. 3 is top plan of the upper removable cap, and repi resents the -location of the series of perforations.

Similar` letters refer to similar parts th rou gh-l out. the several views.

A represents the base or generating portion ofthe burner, provided with a central tube, a.

B is the valve, which is screwed into the bottom of the part A, and may be either a needle or common screw valve, such as is now in use.- i

` C i's a gas-chamber, `which is formed within the cup portion of the base and forms a part of the central tube, and also apart of the outer rim of the cup. This gas-chamber rises above the inlet ofthe gas from the-generator D, and acts upon the same principle as the air-chamber ofa pump to steady the flow, and also as a secondary orsuperheatingchamber. Communication i'romtthe generator D to the gas-chamber C is had through a very small channel, as

It isfound that by this construction` of the lower base ot' the burner all valves, lters, and regulators are dispensed with, as

. the gas contained withinn the chamber C has sufficient force to control the flow ot'tluid, as

said chamber rises above theinlet-oritice of the Huid-conduct.

E is a removable bell-shaped cap having a central hole, which forms a continuation ofthe provided with four rows or series of pert'orations, as in- 5o dicated by letters c c' c 0". The holes in the lower series, c, are square notches cut into the lower edge ot' the cap, and are of a much larger size than the holes inithe other series. The

holes c are located near the edge of the rst 55 terrace, and are drilled so as to emit a vertical llame, while the holes in the series c". are drilled directly into the side ofthe dome at the point ofjunction with the terrace, and they are located intermediately between the series e', so 6o that the dame from each series will not intermingle with each other. At or near the top ot' the dome of this cap is a series of perforatious, 0"', also drilled in horizontally. The direction of the tlame is indicated by curved linesin Fig. 1.

-1t will be obvious that 'the inner bell-shaped cap, E, forms a gas-chamber, or, rather, a combustionchamber, surroundingthe vertical tube a', also enveloping the inner or superheating 7o generator,0. '1t forms a continuation otthe central tube, a', and adds materially toits force.- While this burner may be used successfully without the inner bell-shaped cap, E, caps ot' various forms, having more or less perforations, 7 5

may be used, as"`has been found by actualexperiment. With this base or double generator,

`constructed as shown, the most perfect and satisfactory results are not attained entirely by the specific formation of the upper cap as here- 8o tofore held; but the success liesymainlly in the construction ofthe lower bases of the burner and generators, as herein represented.

As to the inner bell-shaped cap, it is admitted that this adds materially to the power of the generator, and by adding to the power of the generator the force of the llame is proportionately increased, as it confines the flames within the lower or combustion chamber ot' the base of the burner, enveloping the superheat- 9o chamber of the burner, which cast a iiame against the alternate sides of said generator, as shown in Fig. 2.

It vhas been found from actual tests that. the

within-shown terrace-shaped cap, in connection with the inner bell-shaped cap, gives the most perfect combustion and the most intense heat, rendering the flame perfectly odorless by its use in combination with the lower base and its generators.

Having'thus described my invention, what 1 believe to be new, and desire to secure by Letters Patent, is-

1. A vapor-burner having the cup-shaped base A, in combination with the bell-shaped cap E, and the terrace-shaped cap F, provided with the separate series of perforations c e c c, substantially as shown and described.

2. A vapor-burner having the cup-shaped base A,provided with the generating-chamber D and heating-jets e e, and the secondary or gas-superheating chamber C, located above the primary generator D, and connected therewith y emma by a suitable small tube, C', in combination with the terrace-shaped cap F, provided vvithv the series of perforations c c c and depending suitably valved jet tube, substantially as shown and described. A

3. A vapor-burner having the cup-shaped base A, provided with primary generatingchamber D and superheating or secondary chamber G, and suitable connecting-tube leading upward thereinto from the said chamber D, in combination with the removable cap E, the terrace-shaped cap F, provided with the series of perforations c c c" 0', and a depending suitably-valved jet-tube, substantially as shown and described.
